Compared with prior art, the utlity model has following beneficial effect: the hemodialysis adsorber that this utility model provides comprises housing, in housing, be provided with fibrous membrane pipe, the two ends of housing are connected with respectively tremulous pulse end cap and vein end cap, are provided with chitin fiber layer in vein end cap.Hemodialysis adsorber of the present utility model has increased chitin fiber layer in vein end cap, chitin fiber layer has that good virus killing is antibacterial, infection effect, purify blood and prevented antibacterial infection, there is good anticoagulant functions and biocompatibility simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Accompanying drawing indicates as follows: 1-housing, 2-tremulous pulse end cap, 3-vein end cap, 11-fibrous membrane pipe, 12-dialysis solution entrance, 13-drainage plate, the outlet of 14-dialysis solution, 31-chitin fiber layer, 32-filter course.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
Referring to Fig. 1, a kind of hemodialysis adsorber of the present embodiment, a kind of hemodialysis adsorber, comprise housing 1, in housing 1, be provided with fibrous membrane pipe 11, the two ends of housing 1 are connected with respectively tremulous pulse end cap 2 and vein end cap 3, are provided with chitin fiber layer 31 in vein end cap 3, between chitin fiber layer 31 and 3 outlets of vein end cap, are provided with filter course 32.Hemodialysis adsorber of the present utility model is at interior chitin fiber layer 31 and the filter course 32 of having increased of vein end cap 3, chitin fiber layer 31 has that good virus killing is antibacterial, infection effect, purify blood and prevented antibacterial infection, there is good anticoagulant functions and biocompatibility simultaneously, filter course 32 further filters impurity, metabolite in blood, guarantees to flow into that blood in human body is clean, free from admixture.
Preferably, the sidewall of housing 1 is provided with dialysis solution entrance 12 and dialysis solution outlet 14, and the end of dialysis solution entrance 12 is provided with reclinate drainage plate 13.Housing 1 internal cavities forms dialysis chamber, drainage plate 13 changes dialysis solution and enters the direction of dialysis chamber, avoid the impact of dialysis solution to fibrous membrane pipe 11, drainage plate 13 is bent downwardly, make dialysis solution be introduced into dialysis chamber bottom, upruss again, has accelerated particularly dialysis chamber bottom dialysis solution circulation in dialysis chamber, has changed, and has improved dialytic efficiency.
Preferably, the internal diameter of fibrous membrane pipe 11 is 150～165 μ m, and wall thickness is 25～30 μ m.In the present embodiment, adopt than the internal diameter of common dialyzer Guan Geng little and wall thickness, therefore under same film area, can obtain little blood volume, in dialysis procedure, there is less transmembrane pressure, therefore material is shorter in the distance that sees through fiber membranous wall in dialysis procedure, removing material is more prone to, and has improved the dialysis-effect of hemodialysis membrane.
Preferably, chitin fiber layer 31 thickness are 50～300 μ m, and filter course 32 thickness are 10～50 μ m.Ensured that kill virus antibacterial, infection, anticoagulant effect of chitin fiber layer 31 do not affect again the flow of blood.
Work process of the present utility model: dialysis solution is accessed to dialysis solution entrance 12, the entrance of blood samples of patients access tremulous pulse end cap 2, blood and the dialysis solution opposite direction that flows, the metabolite of putting aside in blood and too much water utilization fibrous membrane pipe 11 are discharged in dialysis solution, dialysis solution supplements base to correct acidosis, to adjust electrolyte wadding disorderly by fibrous membrane pipe 11 in blood, blood after dialysis is through chitin fiber layer 31 and filter course 32, finally flowed out and entered human body by the outlet of vein end cap 3, the dialysis solution that contains metabolite exports 14 by dialysis solution and discharges.
Applicant's statement, this utility model illustrates detailed structure of the present utility model and technique by above-described embodiment, but this utility model is not limited to above-mentioned detailed structure and technique, do not mean that this utility model must rely on above-mentioned detailed structure and technique could be implemented.Person of ordinary skill in the field should be understood that; to any improvement of the present utility model; the selections of the equivalence replacement to the each raw material of this utility model product and the interpolation of auxiliary element, concrete mode etc., within all dropping on protection domain of the present utility model and open scope.
